Package        : hunspell-en-us
Version        : 20070829-6+deb7u1

The dictionary provided by this package had an unnecessary unversioned
conflict against the thunderbird package which recently got reintroduced
into Wheezy.

For Debian 7 "Wheezy", this problem has been fixed in version
20070829-6+deb7u1.

We recommend that you upgrade your hunspell-en-us packages.
